The CurrentWatch EDC Series from
Eaton’s electrical business combines
a hall effect sensor and signal
conditioner into a single package for
use in DC current applications up to
300A. The EDC Series has jumperselected current input ranges and
industry standard outputs: 4 – 20
mA, 0 – 5V DC or 0 – 10V DC.
Available in split-core models for
quick and easy installation.
For typical applications of the
CurrentWatch™ EDC Series, see
listing to the right.

CurrentWatch™ Current Sensors
EDC Series Current Sensor
CA05311009E
Current Sensing for DC Loads up to 300A with Analog Outputs
Product Features
Jumper-Selectable Ranges — Reduces inventory and eliminates zero or
■
span pots
■
Isolation — Output is magnetically isolated from the input for safety, also
eliminating insertion loss (voltage drop)
■
Internal Power Regulation — Cuts installation costs and works well, even
with unregulated power
Split Core Design and Built-In Mounting Brackets — Makes installation
■
quick and easy
■
UL and CE Approved
Typical Applications
1
■
Battery Banks — Monitors load current, monitors charging current and
verifies operation
Transportation — Measures traction power or auxiliary loads
■
■
Electric Heating Elements — Monitors heater loads with a faster response
time than temperature sensors
